To all whom it may concern:

Be it known that l, CHARLES E. ENNIS, a citizen ofthe United States.residing at Trinidad, county of Las Animas, State of Colorado, haveinvented certain new and useful Improvements in Raibvaytlrosing Frogs ofwhich the t'olhnving is a specification, reference being bad therein tothe accompanying drawing. a

This invention relates'to a railway crossing frog and particularly to astructure embodymg a swing rail movable from alinentent with one trackrail into alinemcnt with another at an angle thereto.

the invention has for an object to irovide a novel and improvedconstruction of swinging frog rails and of means for locking them inshifted position which means are adapted to be operated by connectionswith an interlocking switch mechanism.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof detined by theappended claims.

In the drawing-"-Figure l is a plan of the invention applied; Fig. 2 isa vertical section of line of Fig. l; and Fig. 3 is a similar section ofline 3- 3 of Fig. 1.

Like numerals of reference. refer to like parts in the several figuresot' the drawing.

The numeral 10 designates the bed plate of the crossing which issuitably supported and provided with extensions 11 disposed beneath theends oi the lived rails 12. This bed plate. may be formed in sections itdesired to facilitate storage and transportation thereof. The fixedrails 12 are secured to the bed plate by means of the angle bars 13,bolted to each of the parts in the usual man ner. 'l'hese plates areformed with an extended portion 14 adapted to lie beneath an end of theswing rails 15. 'l'hese'swing rails are mounted upon a circle plate 16by means of the angle bars 17 bolted to each of the parts, while thecircle plate is sur- .rouuded by an annular plate (37 bolted to. the

bed plate It} as shown in Fig. 2. The circle plate has secured thereto:1. depending bolt 18 passing through the bed plate It) and securedagainstvertical movement thereon by a nut; 19.

For the purpose of moving the swing rails from the position shown byfull lines in big. 1 to that' indicated by dotted lines therein, theserails have secured thereto Specification of Letters Patent. Applicationfiled November 8, 1909.

brackets 20 from which pivoted links 21 extend to a lever bar 22 whichis provided with a lateral arm 23 pivotally connected by links 24 to ashifting connection 25. These parts are similar at opposite ends of thebed plate and are connected to secure the necessary 0p iosite directionsof operation by means o pit-men 26 extending to a ivoted lever 27disposed centrally of the be plate. The shifting connection at one endis con nected to an operating rod 28 extending to an interlockingmechanism or other means for moving the parts.

For the purpose of locking the swing rails in their shifted positions, Ihave pro ided at each end thereof latch 'lretes 30 disposed upon theopposite sides of the rails and properly apcrtured at 31 cooperate withlatch bolts movably mounted upon the bed plate. One set of these boltsis shown at each end of Fig. l and oomprises the bolts 32 ad: ted toenter a casin 33 within which one oi' the plates 30 carried by the swingrail travels when that rail is in alinement with the fixed rail. Thesebolts 32 are operated by means of crank levers 34 connected to a crossbar 35 which is provided at each end with crank levers 36 one of whichis pivotally connected to the operating rod 31' for the bolts while theother is connected to the auxiliary operating rod 3b extending to the,opposite. end of the crossing. At: this end both the operating rod 3?and the auxiliary rod 38 are connected by crank levers 35) to the crossrod It) from which motion is transmitted by the crank lever 34 to thebolts 3:2 as before described. Both the operating rod 37 and theauxiliary rod :58 are pivotally connected to crank levers 4! whichactuate the bolts 42 disposed in casings 43 upon the extensions It bywhich the swing rails may be secured in their shifted position as shownby dotted lilies in Fig. 1. I

l'lxtending between the operating rod 37 and toe auxiliary rod 38 is across bar 45 connected to each thereof by a pivoted crank lever 46. Thisbar has pivoted thereto a lever 47 having a bolt 48 operating in acasing 45) and also with a lever 50 having a bolt 51 operating in thesaid casing tolock the swing bars upon the bed plate when in shiftedpositions. The lever 50 is connected by a. lever 52 with the cross rod45 before described. similar construction til (Fig. 3 m

is used at each side of the crossing. The 'oed plate is provided with asupport 53 over which the inner ends of the swing rails lie when shiftedto the dotted line position shown in Fig. 1.

At each side of the bed plate a latch casing 55 is secured thereto andhas cooperatmounted therein. One of these bolts on each side isconnected b a .lcver 5? to the operating rods 37 and 3t re spcctively,while the other bolt is provided with a similar lever 57 cmnxected by alink 58 to the rock lever 55) pivoted to the operating rods. The bolts56 cooperate with the latch plates 30 carried by the swing rails to holdthem in alinement as shown by full.

In the operation of the inventio: it will be seen that the swing railsof the crossing are held in full line position shown in Fig. l by thebolts 32 and 56. When it desired to swin the rails for alinelncnt with across' track, they are first released through the operating rod 37 andthen shifted through the connection 28 to the dotted line posiiion shownin Fig. 1, after which the latch mechanism is again operated so that thebolts -12. 48 and 51 will respectively engage the latch plates 30carried by the swing rails to hold them in shifted position so that thecrossing is perfectly safe for the movement of a train at full speedthereover without jar or wear to any of the parts. The locking m chanismmay be so connected as to open d d-ailing devices upon the tracksopposite to that with which die swing rails arc alinmi. This structureis mounted so that the swing rails may be readily shifted to preventinterferonce from snow or ice-and when in alinewant, are supported attheir opposite ends. The operating parts of the mechani m here shown maybe properly covered to prevent it from injury or inlerfenence under anyconditions.

The invention presents a simple, -cllicicnt and economically constructedrailway crossing frog adapted to be operated in connection with aninterlocking plant or to be applied to an ordinary crossing conned ions.
